Effects of host age and cocoon position on attack rate by the ...
Host age preference of the hyperparasitoid, Eurytoma sp., attacking the cocoons of the gregarious parasitoid wasp, Cotesia (=Apanteles) glomerata L., was investigated in the field and laboratory. Under laboratory conditions of 20°C and L16D8 photoperiod.
Intraspecific Competition Between Adult Females of the Hyperparasitoid …
Jan 1, 2009 · Here, we examine aggressive interactions between the females of the secondary hyperparasitoid Trichomalopsis apanteloctena (Crawford) (Hymenoptera: Chelonidae), for control of cocoon clusters of their primary parasitoid host …
Hyperparasitoids | NC State Extension - North Carolina State …
Hypopteromalus tabacum is a native hyperparasitoid that attacks Cotesia congregata cocoons after they have emerged from hornworm caterpillars. These wasps will parasitize Cotesia pupae inside cocoons, after the Cotesia have finished feeding inside their hornworm hosts.
Remarkable similarity in body mass of a secondary hyperparasitoid ...
Feb 15, 2006 · Lysibia nana is a solitary, secondary idiobiont hyperparasitoid that attacks newly cocooned pre-pupae and pupae of several closely related gregarious endoparasitoids in the genus Cotesia, including C. glomerata. Prior to oviposition, the female wasp injects paralysing venom into the host, thus preventing further development.
Hyperparasitoids – Erik H. Poelman Research Group
The secondary hyperparasitoid Lysibia nana lays its eggs inside the pupae of parasitoids of the genus Cotesia. It is the most abundant hyperparasitoid in the community of about ten hyperparasitoid species that attack Cotesia. The hyperparasitoids are remarkably effective in locating the parasitoid larvae that seem inconspicuous when developing ...
Host age preference of the hyperparasitoid, Eurytoma sp., attacking the cocoons of the gregarious parasitoid wasp, Cotesia (= Apanteles) glomerata L., was investigated in the field and laboratory. Under laboratory conditions of 20 ~ and LI6D8 photoperiod, Eurytoma sp. parasitized cocoons of all ages, laying 7 to
Development of a solitary koinobiont hyperparasitoid in different ...
Jul 1, 2016 · Mesochorus gemellus is a solitary primary hyperparasitoid of Cotesia species. We compared development of M. gemellus in L3-L5 instars of Pieris brassicae. P. brassicae has been parasitized by Cotesia glomerata in the first instar. Approximately 40% of C. glomerata larvae were parasitized in L3-L5 P. brassicae.
Mechanism and consequences for avoidance of superparasitism …
Jul 10, 2020 · Here, we used microsatellite studies of two distinct populations of Cotesia vestalis to demonstrate that an egg laid into a diamondback moth (Plutella xylostella) larva that was parasitized...
Differing Host Exploitation Efficiencies in Two ... - Springer
Jan 15, 2011 · Host exploitation behavior in two hyperparasitoids, Lysibia nana and Gelis agilis, was compared in single cocoon clusters of their primary parasitoid host, Cotesia glomerata. L. nana reproduces sexually, is fully winged, does not host-feed and matures eggs quite rapidly after eclosion, whereas G. agilis possesses opposite traits.
Symbiotic polydnavirus and venom reveal parasitoid to its ... - PNAS
Apr 30, 2018 · In parasitoid wasps, symbiotic viruses and venom that are injected together with wasp eggs into the host caterpillar suppress immune responses of the host and enhance parasitoid survival. We found that the virus also has negative effects on offspring survival when placing these interactions in a community context.
